VOD playback with seeking in the main content

Scenario

This scenario comprises seeking in the main content during playback.

This is the same scenario as the VOD playback with no ads scenario, but a part of the content is scrubbed through and a seek is completed from one point in main content to another point.

Trigger   Heartbeat method   Network calls   Notes  
User clicks Play trackSessionStart Analytics Content Start, Heartbeat Content Start The measurement library is unaware that there is a pre-roll ad, so these network calls are identical to the VOD playback with no ads scenario.
First frame of the content plays. trackPlay Heartbeat Content Play When chapter content plays before main content, the Heartbeats start when the chapter starts.
Content plays Content Heartbeats This network call is exactly the same as the VOD playback with no ads scenario.
User begins seek operation on content trackSeekStart No heartbeats go out till seek is complete, for example, trackSeekComplete
Seek operation completes trackSeekComplete Heartbeats begin to go out since seek is complete. Tip: The playhead value should represent the correct new playhead after the seek.
Content is complete trackComplete Heartbeat Content Complete This network call is exactly the same as the VOD playback with no ads scenario.
Session Over trackSessionEnd SessionEnd

Sample Code

In this scenario, the user is seeking when the main content is being played.

Android

To view this scenario in Android, set up the following code:

// Set up mediaObject 
MediaObject mediaInfo = MediaHeartbeat.createMediaObject( 
  Configuration.MEDIA_NAME,  
  Configuration.MEDIA_ID,  
  Configuration.MEDIA_LENGTH,  
  MediaHeartbeat.StreamType.VOD 
); 

HashMap<String, String> mediaMetadata = new HashMap<String, String>(); 
mediaMetadata.put(CUSTOM_KEY_1, CUSTOM_VAL_1); 
mediaMetadata.put(CUSTOM_KEY_2, CUSTOM_VAL_2); 

// 1. Call trackSessionStart() when the user clicks Play or if autoplay is used,  
//    i.e., there is an intent to start playback.  
_mediaHeartbeat.trackSessionStart(mediaInfo, mediaMetadata); 

...... 
...... 

// 2. Call trackPlay() when the playback actually starts, i.e., whn the first frame  
//    of the main content is rendered on the screen.  
_mediaHeartbeat.trackPlay(); 

....... 
....... 

// 3. Track the MediaHeartbeat.Event.SeekStart event when the user begins to seek.  
_mediaHeartbeat.trackEvent(MediaHeartbeat.Event.SeekStart, null, null); 

....... 
....... 

// 4. Track the MediaHeartbeat.Event.SeekComplete event when the user completes seeking 
_mediaHeartbeat.trackEvent(MediaHeartbeat.Event.SeekComplete, null, null); 

....... 
....... 

// 5. Call trackComplete() when the playback reaches the end, i.e., when the media 
//    completes and finishes playing. 
_mediaHeartbeat.trackComplete(); 

........ 
........ 

// 6. Call trackSessionEnd() when the playback session is over. This method must be  
//    called even if the user does not watch the media to completion.  
_mediaHeartbeat.trackSessionEnd(); 

........ 
........ 

iOS

To view this scenario in iOS, set up the following code:

// Set up mediaObject 
ADBMediaObject *mediaObject =  
[ADBMediaHeartbeat createMediaObjectWithName:MEDIA_NAME o 
                   length:MEDIA_LENGTH  
                   streamType:ADBMediaHeartbeatStreamTypeVOD]; 
 
NSMutableDictionary *mediaContextData = [[NSMutableDictionary alloc] init]; 
[mediaContextData setObject:CUSTOM_VAL_1 forKey:CUSTOM_KEY_1]; 
[mediaContextData setObject:CUSTOM_VAL_2 forKey:CUSTOM_KEY_2]; 

// 1. Call trackSessionStart when the user clicks Play or if autoplay is used,  
//    i.e., there is an intent to start playback. 
[_mediaHeartbeat trackSessionStart:mediaObject data:mediaContextData]; 
....... 
....... 

// 2. Call trackPlay when the playback actually starts, i.e., when the 
//    first frame of the main content is rendered on the screen. 
[_mediaHeartbeat trackPlay];  
....... 
....... 

// 3. Track the trackEvent:ADBMediaHeartbeatEventSeekStart event when the user  
//    begins to seek out of the chapter with the intent to skip it. 
[_mediaHeartbeat trackEvent:ADBMediaHeartbeatEventSeekStart  
               mediaObject:nil  
               data:nil]; 
....... 
....... 

// 4. Track the trackEvent:ADBMediaHeartbeatEventSeekComplete event when the  
//    user seeks out of the chapter with the intent to skip it. 
[_mediaHeartbeat trackEvent:ADBMediaHeartbeatEventSeekComplete  
               mediaObject:nil  
               data:nil]; 
....... 
....... 

// 5. Call trackComplete when the playback reaches the end, i.e., completes  
//    and finishes playing. 
[_mediaHeartbeat trackComplete]; 
....... 
....... 

// 6. Call trackSessionEnd when the playback session is over. This method must  
//    be called even if the user does not watch the media to completion. 
[_mediaHeartbeat trackSessionEnd]; 
.......
